Abstract: A 2000 series aluminum alloy characterized by high strength, very high fatigue resistance, and very high fracture toughness consists essentially of3.8%to 4.4 % copper, 1.2%to 1.8% magnesium, 0.3% to 0.9% manganese, maximums of 0.12% silicon, 0.15% iron, 0.25% zinc, 0.15 % titanium, 0.10% chromium, 0.05%of each of any othertrace elements present, and a maximum total of such other trace elements of 0.15%, the balance of the alloy being aluminum. It is preferred, especially for plate products, that the maximum iron and silicon levels be restricted to 0.12% and 0.10%, respectively. For extruded products, the foregoing alloy is hot worked to yield a wrought product having a substantially unrecrystallized structure. For plate products, the alloy is subjected to room temperature preaging and a cold rolling treatment to provide a reduction in gauge of from 9% to 13%.

Abstract: Relatively uniform air laid webs of paper making fiber are produced by dispersing fibers of the order of 6 mm long in air and conveying them as a stream in air obliquely to a moving web-forming surface (12), the rate of travel (V 0 ) of the forming surface (12) being not less than 2.54 m/sec. To achieve uniform webs, the stream of air and fibers is given a component of velocity (V 1 ) in the direction of travel of the forming surface, and a component of velocity (V 2 ) normal to the forming surface, related to one another and to V a  such that the difference between V 0  and V 1  is less than 3 times V 2 .

Abstract: A scanning apparatus wherein the illumination scanning means (32) employed travels at a rate which is greater than that of a flat photoreceptor (42) moving in the same direction. In one embodiment, a dual rate mirror assembly (34,38) scans a document (30) on a platen at a first rate which is greater than the process speed set for a photoreceptor belt. The image is projected through a lens (4U) and precessed by a mirror arrangement (41) along the belt surface in a direction opposite to the belt travel. The precession rate can be set relative to the scanning flyback time, so as to reduce or eliminate an interdocument gap on the photoreceptor and to lower process speeds for a given copy rate.

Abstract: An optical scanning apparatus is provided which imagewise exposes the surface of a photoreceptor drum (28) at a rate faster than the rate at which an object (13) is scanned. In a preferred embodiment, a dual-rate mirror assembly (14,18) is driven at a speed greater than the process speed of the photoreceptor drum. A movable reflector (26) mounted adjacent the drum reflects the image in precession fashion along the drum surface in a direction opposite the drum rotation. The time gained due to the precession of the image along the drum surface enables the dual-rate mirror assembly to return (flyback) to its start-of-scan position, thereby maximising copy output.

Abstract: A directional lamp shade having a hollow tubular body (10) to be fitted to light source (13) and having an open exit end. The length (14) of the body is chosen to prevent direct light passing through the open end outside a predetermined cone semi-angle (y). The body has a plurality of baffles (15) in the form of annular disks which prevent an observer looking through the body open end from outside the light cone and seeing directly illuminated portions of the body inner surface. The inner edges of the disks are sharpened to . minimise specular and diffuse reflections therefrom. The disks may be equally spaced.

Abstract: The process of separating components of a crude reaction mixture obtained from a molybdenum-catalyzed hydroperoxide epoxidation of an olefin wherein the product epoxide and an alcohol corresponding to the hydroperoxide used are removed from the reaction mixture leaving a spent catalyst solution and subjecting the spent catalyst solution to a liquid-to-liquid solvent extraction to separate dissolved molybdenum values, is improved by solvent extracting the spent catalyst solution with an extracting medium consisting essentially of water and a water immiscible organic solvent to form a two phase system and then separating the molybdenum-rich aqueous phase extract from the organic phase extract. The molybdenum-rich aqueous phase extract may be treated to recover the molybdenum as a solid or the extract may be treated to obtain an active molybdenum catalyst suitable for reuse as a catalyst in a hydroperoxide epoxidation reaction.
